Title: Character feature extracting system
Inventor: ISAKI YASUNAO
IPC: G06K9/46
Filed: 1989-12-20
Abstract: PURPOSE:To improve the character recognition accuracy by allocating a direction code to each picture element of a character part which becomes a recognition object, and setting the minimum distance between each point on a circumscribed polygon and an object direction component image (its direction component image) as a feature quantity of its point, that is, a vector component, with regard to each direction component image. CONSTITUTION:A character recognizing device 20 segments the part corresponding to one character from an input character-string, and forms a circumscribed polygon circumscribed to its segmented character part. A character code allocating part 11 executes a processing for allocating a direction code to each picture element of the segmented character part. A collating part 13 collates a feature vector of an input character image derived in such a way and a feature vector of each standard pattern, based on the feature quantity of each point, selects each character of a standard pattern whose degree of difference is below a prescribed value or a standard pattern whose degree of similarity is above a prescribed value, and outputs it as a candidate character-string. The character recognizing part 20 executes the post-processing for collating this candidate character-string with a word dictionary and a word connection rule, etc., and outputs it as a recognized character. In such a way, the character recognition accuracy can be improved.

Title: Design inspecting method for printed wiring board
Inventor: MATSUZAKA HIDETOSHI
IPC: G06F17/50
Filed: 1990-11-30
Abstract: PURPOSE:To reduce man-hours and erroneous input by substituting grouping data which are outputted from a wiring inspection program for logical connection data which are manually inputted and correcting only an intended part. CONSTITUTION:The logical connection data which are manually inputted before are automatically generated by copying the grouping data in a logical connection information file. The logical connection data which are automatically generated includes erroneous input at the time of layout designing with high possibility, so the erroneous input is pointed out and correcting operation is newly required. This operation is relatively easy by pointing out different point erroneous (input) by matching the data with a logical circuit diagram. Thus, the logical connection data after the erroneous input is corrected and the original grouping data are inputted to a wiring inspection program and the position of erroneous wiring at the time of the layout designing is found from the acceptance/rejection decision result. Consequently, the man-hours and erroneous input are reducible.
